oracle的自增需要依靠序列和触发器共同实现
比如 新建一张表
create table test
(id int primary key,name varchar2(10));创建一个序列
create sequence test_seq increment by 1 start with 1
minvalue 1 maxvalue 9999999999999 nocache order;触发器实现
create or replace trigger test_trigger
before insert on testfor each rowbegin select test_seq.Nextval into:new.id from dual;end;然后插入数据
insert into test (name) values (‘张三‘);
